Email Spam-the Never ending Cat and Mouse Game

Today – as before – there is plenty of spam on social networks and in other types of online marketing, but most of us probably think of email when talking about spam. If you’re like me, battling email spam is a never-ending game of cat and mouse — tweaking spam filter settings, blacklisting and whitelisting domains, deleting emails that reach the In box, etc.
If your Website is build on the WordPress CMS System and you are using the popular Contact Form 7 Plugin for your Contact Form then here are some additional solutions apart from the build in re Captcha Integration.

First off – Should You use all the anti-spam methods recommended here?

In a word, no. I do NOT recommend that you implement ALL of the methods suggested in this article. A WordPress website should be kept as clean and minimal as possible behind the scenes, and you should not install unnecessary plugins.
Instead, I recommend using trial and error to experiment with these solutions – whether you’re a WordPress expert or a novice.If you need Help with any of these methods please contact me. Track how much contact form spam you receive after implementing one or two methods, and make changes until you are happy. Install Akismet as a starting point, and take it from there.

Using Contact Form 7’s in-built anti-spam measures

You’ll find a lot of articles recommending CAPTCHA and quiz plugins that work with Contact Form 7. Most of these are unnecessary as it’s better to use the features already built into the Contact Form 7 WordPress plugin.

Quiz

Simple quizzes are becoming a popular way to combat contact form spam. They work by asking the user a simple question such as “Which is bigger, 2 or 8?” Bots can’t answer this question. As a result, only people who enter the correct response can submit the contact form.

To add a quiz, edit your contact form and click the Generate Tag dropdown. Paste the shortcode that appears below into your contact form. It will look something like this:

[quiz capital-quiz "Which is bigger, 2 or 8?|8"]

2. Minimum character count

The WordPress website featured in this article received a lot of spam contact forms with 2-digit messages – usually a number. I have no idea what they were trying to achieve, but it’s obviously a popular type of spam at the moment.

If all your spam messages follow an obvious pattern, you can block them by setting up your contact form to block messages that meet this pattern. In this case, I used the Max and Min Length options in Contact Form 7 to require messages to be more than 20 characters long. Genuine inquiries will usually provide more than 20 characters, so this blocks bots without frustrating real users.

The Message/Comments field will look something like this:

[textarea* your-message minlength:20 maxlength:500]

3. Akismet

Akismet has a reputation as the best WordPress anti-spam plugin. Not everyone knows that it works with Contact Form 7 as well as blog comments.

Once you have activated the Akismet WordPress plugin and followed the on-screen instructions to add your API key (free for non-profit-making website, small monthly fee for business sites), you need to do a bit of extra config to make it talk to Contact Form 7 – see https://contactform7.com/spam-filtering-with-akismet/.

In my tests, Akismet stopped about 70% of the Contact Form 7 spam but not all of it. It worked well in conjunction with some of the other solutions mentioned in this article.

4. Contact Form 7 Honeypot

Contact Form 7 Honeypot is a WordPress plugin that adds a hidden field to your contact form. Real users won’t complete it because the field is invisible. However bots won’t know this and will fill it in. This allows the plugin to recognize them as bots and block their submission.

After you have installed and activated the Contact Form 7 Honeypot WordPress plugin, use the Generate Tag option to create a honeypot shortcode to insert into your contact form. It will look something like this (Contact Form 7 recommend changing the ID to something unique, so replace 531 with something else):

5. Really Simple CAPTCHA

The Really Simple CAPTCHA WordPress plugin was created by the developer of Contact Form 7 so they work together seamlessly. The plugin allows you to add a CAPTCHA to your contact form. It’s designed to prevent bots from submitting forms on your WordPress website.

Once you have installed and activated Really Simple CAPTCHA, insert a CAPTCHA tag into your Contact Form 7 form. (Click the Generate Tag dropdown to see the available options and create a customized tag to paste into your form.) It will look something like this:

Please note that CAPTCHAs are becoming slightly old fashioned and are not great for user-experience. They also require particular features to be enabled on your server, which may not be in place for your WordPress website.

I would recommend adding a quiz first (see above), and only trying CAPTCHA if this doesn’t work. The two methods basically do the same thing. They prevent automated bots from submitting your website contact form – so you shouldn’t need both.

If you just want to add one method to reduce Contact Form 7 spam, then I recommend Akismet. This is the best standalone solution as it’s so powerful and comprehensive. You can use it whether you’re a WordPress expert or a beginner. It can make a real difference to your WordPress contact form spam.
